Phosphate-Modified Polyphenol Polymers for Fire Resistance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional fire-resistant thermoplastics and thermosetting resins often contain halogens, which generate toxic gases upon combustion, whereas the incorporation of phosphate groups into these materials results in the formation of non-volatile phosphoric acid, enhancing fire resistance and reducing toxicity.
Innovation Solution
Methods for synthesizing fire-resistant polymeric materials by reacting polyphenols, such as trans-resveratrol, with halophosphates to introduce phosphate groups, allowing for the formation of phosphate-containing polymers and thermoset networks with controlled molecular weight and thermal properties, and combining these with support materials to create composite materials.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If halogens are incorporated into thermoplastics and thermosetting resins to achieve fire resistance, then fire resistance is improved, but toxic gases are generated upon combustion
Solution Approach 1:
The patent changes the chemical composition parameter by replacing halogen elements with phosphate groups in the polymer structure. This substitution maintains fire resistance while fundamentally altering the combustion products from toxic halogenated gases to non-volatile phosphoric acid, thereby resolving the contradiction between fire safety and toxicity reduction
Solution Approach 2:
The patent converts the potential harm of phosphate groups (which can increase material complexity and require new synthesis methods) into a benefit by demonstrating that phosphate-containing polymers produce non-volatile phosphoric acid during combustion. This transforms the chemical composition change into a dual benefit: maintaining fire resistance while eliminating toxic gas generation
2Reliability
If phosphate groups are incorporated into thermoplastics and thermosetting resins, then fire resistance and reduced toxicity are achieved, but material complexity increases
Solution Approach 1:
The patent employs composite material strategies by incorporating phosphate groups into polyphenol structures to create new fire-resistant materials. The methodology systematically addresses the complexity challenge by providing structured synthesis approaches for phosphate-containing monomers and polymers, transforming a potentially complex chemical modification into a manageable and scalable process
3Reliability
If phosphate groups are incorporated into polyphenols, then fire resistance is enhanced, but synthesis complexity increases
Solution Approach 1:
The patent applies segmentation by dividing the synthesis process into distinct stages: first synthesizing phosphate-containing monomers with controlled molecular weight, then polymerizing these monomers into final polymeric materials. This segmented approach breaks down the complex synthesis into manageable steps, reducing overall manufacturing complexity while maintaining fire resistance
Solution Approach 2:
The patent implements preliminary action by pre-synthesizing phosphate-containing monomers with specific molecular weights and functional groups before polymerization. This preliminary preparation allows for better control over the final polymer properties and simplifies the overall manufacturing process by separating monomer synthesis from polymer formation
